determining whether myocardial ischemia exists;
if myocardial ischemia exists, determining whether the ischemia is local or global;
if the ischemia is local, delivering a therapy comprising a first number of successive shocks separated by a first shock-to-shock
time;
if the ischemia is global, delivering a therapy comprising a second number of successive shocks separated by a second shock-to-shock
time, wherein the second number of successive shocks is greater than the first number of successive shocks and the second
shock-to-shock time is greater than the first shock to shock time.
